Effect of Variations in the Ring Thickness on the Dynamic Performance of the Bimetal Gears
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This study used a six‐degrees‐of‐freedom dynamic model to analyze the dynamic response of bimetal spur gears. Aluminum alloy forms the core of the bimetal gears, and a uniform‐thickness steel ring surrounds the teeth. Gear mesh stiffness of bimetal gears and the transmission error have been assessed using a numerical approach based on finite ...
